生态水网建设对邯郸市地下水环境的影响

The Effect of Ecological Water Network Construction on Groundwater Environment in Handan

为解决水资源供需矛盾、合理利用水资源,2006年邯郸市建设生态水网工程。本文采用内梅罗综合指数法,对2005年、2010年、2015年地下水水质监测数据进行评价,对主要污染物质的变化趋势进行分析,以掌握生态水网的实施对该市地下水水环境的影响。结果表明:部分监测井的溶解性总固体、总硬度、氯化物、硫酸盐、氨氮、硝酸盐氮、亚硝酸盐氮、高锰酸盐等主要污染物呈明显下降趋势,10处监测井的F值呈减小趋势。由此可见,生态水网的实施对该市地下水环境有明显改善。

To solve the contradiction between water supply and demand,and use water resources rationally,ecological water network projects were constructed in Handan city in 2006. Nemerow Synthetical Index Method was adopted in this paper to evaluate groundwater quality monitoring data in 2005,2010 and 2015,respectively. Trends of the main pollutants were analyzed to understand the influence of implementing ecological water network on groundwater environment. The results indicated that the main pollutants such as Total Soluble Solids,Total Hardness,Chloride,Sulfate,Ammonia Nitrogen,Nitrate Nitrogen,Nitrite Nitrogen,Potassium Permanganate,etc. in some monitoring wells had obvious downward trend. F values in 10 wells had decrease trend. Thus,it can be seen that the implementation of ecological water network has evident improvements on groundwater environment in Handan.
